SCP&L A Progress EnergyCompany MAR 2 2 2002 SERIAL: BSEP 02-0059 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NO. 1 DOCKET NO. 50-325/LICENSE NO. DPR-71 UNIT 1 CYCLE 14 CORE OPERATING LIMITS REPORT, SUPPLEMENTAL RELOAD LICENSING REPORT, LOSS-OF-COOLANT ACCIDENT ANALYSIS REPORT, AND PLANT-SPECIFIC EMERGENCY CORE COOLING SYSTEM (ECCS) EVALUATION Ladies and Gentlemen:

The purpose of this letter is to submit the latest revision of the Core Operating Limits Report, Supplemental Reload Licensing Report, and Loss-of-Coolant Accident Analysis Report for Carolina Power & Light (CP&L) Company's Brunswick Steam Electric Plant (BSEP), Unit No. 1. This letter also provides notice that the Emergency Core Cooling System (ECCS) evaluation model for Unit 1 now includes GE14 fuel type information. These reports are applicable to operation at the maximum power level currently authorized by the facility operating license (i.e., 2558 megawatts thermal). Revisions to these reports will be submitted following NRC approval of CP&L's extended power uprate application, prior to operation above 2558 megawatts thermal.

Technical Specification 5.6.5.d requires that the Core Operating Limits Report be provided to the NRC, upon issuance, for each reload cycle. A copy of "Brunswick Unit 1, Cycle 14 Core Operating Limits Report March 2002," Revision 0, is provided in Enclosure 1. The NRC's Safety Evaluation for Amendment 19 to General Electric Licensing Topical Report NEDE-2401 1-P-A (i.e., GESTAR-II), "General Electric Standard Application For Reactor Fuel," states that the Technical Specifications will include, for each multiple lattice fuel bundle type, a plot of the limiting value of Average Planar Linear Heat Generation Rate (APLHGR) for the most limiting lattice as a function of exposure. Consistent with the guidance in NRC Generic Letter 88-16, "Removal of Cycle-Specific Parameter Limits From Technical Specifications," the limiting value of APLHGR for the most limiting lattice, as a function of exposure, has been relocated from the Technical Specifications to the Core Operating Limits Report. A plot of the limiting value of APLHGR, as a function of average planar exposure for each reload fuel type, is included in the enclosed Core Operating Limits Report.

The NRC's Safety Evaluation for Amendment 19 to GESTAR-II also states that each reload submittal should include a table of the most limiting and least limiting Maximum Planar Brunswick Nuclear Plant PO. Box 10429 Southport, NO 28461 Vv,

Document Control Desk BSEP 02-0059 / Page 2 Linear Heat Generation Rate (MAPLHGR) for each multiple lattice bundle type. A copy of "Supplemental Reload Licensing Report for Brunswick Steam Electric Plant Unit 1 Reload 13 Cycle 14," JI 1-03936SRLR, Revision 1, Class I, dated January 2002, is provided in Enclosure 2. The most limiting and least limiting MAPLHGR values for the new reload fuel types are provided in a table included in the Supplemental Reload Licensing Report for BSEP, Unit 1.

The NRC's Safety Evaluation for Amendment 19 to GESTAR-II states that each licensee should submit to the NRC, on a proprietary basis, information for each fuel bundle type on the axial location of each lattice in the bundle and composite MAPLHGR as a function of average exposure for each lattice in the bundle. A copy of "Loss-of-Coolant Accident Analysis Report for Brunswick Steam Electric Plant Unit 1 Reload 13 Cycle 14,"

NEDC-31624P, Supplement 1, Revision 6, Class III, dated November 2001, is provided in . This report contains MAPLHGR, as a function of exposure, for each lattice of the fuel designs.

Global Nuclear Fuel considers portions of the Loss-of-Coolant Accident Analysis Report in to be proprietary information, as indicated by the bars drawn in the margin of the report. Therefore, the document should be withheld from public disclosure in accordance with 10 CFR 9.17 and 10 CFR 2.790. An affidavit supporting the request for withholding the document is provided in Enclosure 4.

By letter dated December 7, 2000 (Serial: BSEP 00-0165), CP&L submitted the results of a reanalysis of the limiting ECCS evaluation model for BSEP, Units 1 and 2. This letter stated that the GE7, GE8, GE9, and GEl0 fuel types are no longer used in BSEP reactor cores; therefore, only results applicable to the GE13 fuel type would be considered the licensing basis for BSEP. Beginning with Cycle 14, the Unit 1 reactor core will include GE14 fuel.

Therefore, the licensing basis ECCS evaluation model for BSEP, Unit 1 will now also include GE14 fuel type information. GE14-specific ECCS evaluation information applicable to both BSEP units is contained in a document entitled "Brunswick Steam Electric Plant Units 1 and 2 ECCS-LOCA Evaluation for GE14," GE-NE-J1103781-09-02P, DRF J11-03781-09, Class III, dated February 2001, a copy of which has been previously submitted as of CP&L's letter dated March 16, 2001 (i.e., NRC ADAMS Accession Number ML010790186).

This report provides the values of the power distribution limits and control rod withdrawal block instrumentation setpoints for Brunswick Unit 1, Cycle 14 as required by TS 5.6.5.

OPERATING LIMIT REQUIREMENT Average Planar Linear Heat Generation Rate (APLHGR) limits TS 5.6.5.a. 1 (with associated core flow and core power adjustment factors)

Minimum Critical Power Ratio (MCPR) limits TS 5.6.5.a.2 (with associated core flow and core power adjustment factors)

Period Based Detection Algorithm (PBDA) Setpoint for Function 2.f of TS 5.6.5.a.3 TS 3.3.1.1, Oscillation Power Range Monitor (OPRM)

Allowable Values and power range setpoints for Rod Block Monitor TS 5.6.5.a.4 Upscale Functions of TS 3.3.2.1 Scram values of the APRM Simulated Thermal Power-High Allowable TS 3.3.1.1 Value ("Flow-Biased Scram")

Control Rod Block values of the APRM - Upscale Allowable Value TRMS 3.3

("Flow-Biased Rod Block")

Per TS 5.6.5.b and 5.6.5.c, these values have been determined using NRC approved methodology and are established such that all applicable limits of the plant safety analysis are met.

The limits specified in this report support single loop operation (SLO) as required by TS LCO 3.4.1 and inoperable Main Turbine Bypass System as required by TS 3.7.6.

In order to support the Stability Option III with an inoperable OPRM scram function, the following is also included in this report:

OPERATING LIMIT REQUIREMENT BWROG Interim Corrective Action Stability Regions TS 3.3.1.1 LCO Condition I CP&L A Progress Enetgy C~onwm

CP&L Nuclear Fuels Mgmt. & Safety Analysis Design Calc. No. 1B21-0604 B1C14 Core Operating Limits Report Page 6, Revision 0 This report conforms to Quality Assurance requirements as specified in Reference 1.

Single Loop Operation Brunswick Unit 1, Cycle 14 may operate over the entire MEOD range with Single recirculation Loop Operation (SLO) as permitted by TS 3.4.1 with applicable limits specified in the COLR for TS LCO's 3.2.1, 3.2.2 and 3.3.1.1. The applicable limits are:

LCO 3.2.1, Average Planar Linear Heat Generation Rate (APLHGR) Limits: per Reference 1, the Figures 9 andl0 described in the APLHGR Limits section below include a SLO limitation of 0.8 on the MAPLHGR(F) and MAPLHGR(P) multipliers.

LCO 3.2.2, Minimum Critical Power Ratio (MCPR) Limits: per Reference 1, Table 1 and Figures 11 and 12, the MCPR limits presented apply to SLO without modification.

LCO 3.3.1.1, Reactor Protection System Instrumentation Function 2.b (Average Power Range Monitors Simulated Thermal Power - High) Allowable Value: per footnote b, the -AW offset value is defined in Plant procedures. The current value of 5% developed for the initial installation of Stability Option III is used for the B 1C 14 COLR.

Inoperable Main Turbine Bypass System Brunswick Unit 1, Cycle 14 may operate with an inoperable Main Turbine Bypass System in accordance with TS 3.7.6 with applicable limits specified in the COLR for TS LCO 3.2.1 and 3.2.2.

Two or more bypass valves inoperable renders the System inoperable, although the Turbine Bypass Out-of-Service (TBPOOS) analysis supports operation with all bypass valves inoperable for the entire MEOD range and up to 110 F rated equivalent feedwater temperature reduction. The system response time assumed by the safety analyses from event initiation to start of bypass valve opening is 0.10 seconds, with 80% bypass flow achieved in 0.30 seconds. The applicable limits are as follows:

LCO 3.2.1, Average Planar Linear Heat Generation Rate (APLHGR) Limits: in accordance with Reference 1 as shown in Figure 10, TBPOOS does not require an additional reduction in the MAPLGHR(P) limits between 25% and 30% power, as the Turbine bypass Operable and Inoperable limits are identical.

LCO 3.2.2, Minimum Critical Power Ratio (MCPR) Limits: in accordance with Reference 1, TBPOOS does not require an additional increase in the MCPR(P) multiplier between 25% and 30% power, as shown in Figure 12, as the Turbine bypass Operable and Inoperable limits are identical. TBPOOS requires increased MCPR limits, included in Table 1.

CP&L Nuclear Fuels Mgmt. & Safety Analysis Design Calc. No. 1B21-0604 B1C14 Core Operating Limits Report Page 7, Revision 0 APLHGR Limits The limiting APLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of planar average exposure is given in Figures 1 through 7. These values were determined with the SAFER/GESTR LOCA methodology described in GESTAR-Il (Reference 2).

Figures 1 through 7 are to be used only when hand calculations are required as specified in the bases for TS 3.2.1. Hand calculated results may not match a POWERPLEX calculation since normal monitoring of the APLHGR limits with POWERPLEX uses the complete set of lattices for each fuel type provided in Reference 3.

The core flow and core power adjustment factors for use in TS 3.2.1 are presented in Figures 9 and

10. For any given flow/power state, the minimum of MAPLHGR(F) determined from Figure 9 and MAPLHGR(P) determined from Figure 10 is used to determine the governing limit.

MCPR Limits The ODYN OPTION A, ODYN OPTION B, and non-pressurization transient MCPR limits for use in TS 3.2.2 for each fuel type as a function of cycle average exposure are given in Table 1. These values were determined with the GEMINI methodology and GEXL-PLUS critical power correlation described in GESTAR-I1 (Reference 2), and are consistent with a Safety Limit MCPR of 1.12 specified by TS 2.1.1.2.

The core flow and core power adjustment factors for use in TS 3.2.2 are presented in Figures 11 and

12. For any given power/flow state, the maximum of MCPR(F) determined from Figure 11 and MCPR(P) determined from Figure 12 is used to determine the governing limit.

All MCPR limits presented in Table 1, Figure 11 and Figure 12 apply to two recirculation pump operation and SLO without modification.

RBM Rod Block Instrumentation Setpoints The nominal trip setpoints and allowable values of the control rod withdrawal block instrumentation for use in TS 3.3.2.1 (Table 3.3.2.1-1) are presented in Table 2. These values were determined consistent with the bases of the ARTS program and the determination of MCPR limits with the GEMINI methodology and GEXL-PLUS critical power correlation described in GESTAR-II (Reference 2). Reference 8 revised certain of these setpoints to reflect changes associated with the installation of the new PRNM system.

CP&L Nuclear Fuels Mgmt. & Safety Analysis Design Calc. No. 1B21-0604 B1C14 Core Operating Limits Report Page 8, Revision 0 Stability Option III Brunswick Unit 1 has implemented BWROG Long Term Stability Solution Option III (Oscillation Power Range Monitor-OPRM) as described in Reference 4. Plant specific analysis incorporating the Option III hardware is described in Reference 5. Reload validation has been performed in accordance with Reference 6. The resulting stability based MCPR Operating Limit is provided for two conditions as a function of OPRM amplitude setpoint in Table 3. The reload validation calculation demonstrated that reactor stability does not produce the limiting OLMCPR for Cycle 14 as long as the selected OPRM setpoint produces values for OLMCPR(SS) and OLMCPR(2PT) which are less than the corresponding acceptance criteria. Because the acceptance criteria for OLMCPR(SS) is 1.50 and for OLMCPR(2PT) is 1.40, an OPRM setpoint (Amplitude Setpoint Sp) of 1.15 is supported for Cycle 14 without imposing any additional operational restrictions for stability protection. Therefore the OPRM PBDA setpoint limit referenced by function 2.fofTable 3.3.1.1-1 of Technical Specification 3.3.1.1 is 1.15 for Cycle 14. Per Table 3-2 of Reference 6, an Sp value of 1.15 supports selection of a Confirmation Count Setpoint Np of 16 or less.

Four Power/Flow maps (Figures 13-16) were developed based on Reference 7 to facilitate operation under Stability Option III as implemented by function 2.f of Table 3.3.1.1-1 and LCO Condition I of Technical Specification 3.3.1.1. The corresponding Reference 7 maps are simply re-formatted (no change in data) to exhibit the appropriate headers for the COLR. All four maps illustrate the region of the power/flow map above 25% power and below 60% flow where the system is required to be enabled.

The maps supporting an operable OPRM function 2.f (Figures 13 and 15) show the same Scram Avoidance Region, which is not a licensing requirement but is an operator aid to illustrate where the OPRM system is reasonably likely to generate a scram to avoid an instability event. Figures 13 and 15 differ only in that the Figure 15 that supports SLO, indicates the maximum allowable core flow at 45 Mlbs/hr, and has the Simulated Thermal Power (STP) scram and rod block limits appropriately reduced for SLO. Note that the STP scram and rod block limits are defined in Technical Specifications, the Technical Requirements Manual, and Plant procedures, and are included in the COLR as an operator aid rather than a licensing requirement.

The maps (Figures 14 and 16) supporting an inoperable OPRM function 2.f show the BWROG-94078 Interim Corrective Actions stability regions required to support LCO Condition I.

Both figures also include a 5% Buffer Region around the Immediate Exit Region as an operator aid.

Figures 14 and 16 differ only in that the Figure 16 that supports SLO, indicates the maximum allowable core flow at 45 Mlbs/hr, and has the scram and rod block flow-biased limits appropriately reduced for SLO.

10. Local Rod Withdrawal Error (With Limiting Instrument Failure) AOO Summary The rod withdrawal error (RWE) event in the maximum extended operating domain was originally analyzed in the GE BWR Licensing Report, Maximum Extended Operating Domain Analysis for Brunswick Steam Electric Plant, NEDC-31654P, February 1989. The Cycle 14 analysis resulted in a RWE ACPR of 0.11 (which is bounded by the generic ARTS ACPR of 0.14) at a rod block monitor setpoint of 108%. The MCPR for rod withdrawal error is bounded by the safety limit adjusted operating limit MCPRs in Table 10-5(a) or 10-5(b) of NEDC-31654P. In addition, the RBM System setpoints shown in Table 10-5(c) of NEDC-31654P are supported for Brunswick Unit 1 Cycle 14. The RBM operability requirements specified in Section 10.5 of NEDC-31654P have been evaluated and shown to be sufficient to ensure that the Safety Limit MCPR and cladding 1% plastic strain criteria will not be exceeded in the event of an unblocked RWE event.

U lJ I Should the Option M OPRM system be declared inoperable, the BWROG Interim Corrective Action will constitute the stability licensing basis for Brunswick Unit 1 Cycle 14.

Stability Option III Brunswick Unit 1 has implemented BWROG Long Term Stability Solution Option III (Oscillation Power Range Monitor-OPRM) as described in NEDO-31960-A, "BWR Owners Group Long-Term Stability Solutions Licensing Methodology", November 1995. Plant specific analysis incorporating the Option III hardware is described in GE-NE-C51-00251-00-01, Revision 0, "Licensing Basis Hot Bundle Oscillation Magnitude for Brunswick I and 2", March 2001.

Reload validation has been performed in accordance with NEDO-32465-A, "Reactor Stability Detect and Suppress Solutions Licensing Basis Methodology for Reload Application", August 1996. The stability based MCPR Operating Limit is provided for two conditions as a function of OPRM amplitude setpoint in the following table. The two conditions evaluated are for a postulated oscillation at 45 %

core flow steady state operation (SS) and following a two recirculation pump trip (2PT) from the limiting full power operation state point. Current power and flow dependent limits provide adequate protection against violation of the Safety Limit MCPR for postulated reactor instability as long as the operating limit is greater than or equal to the specified value for the selected OPRM setpoint.

The stability-based OLMCPR was calculated for Cycle 14. The reload validation calculation demonstrated that reactor stability does not produce the limiting OLMCPR for Cycle 14 as long as the selected OPRM setpoint produces values for OLMCPR(SS) and OLMCPR(2PT) which are less than the corresponding acceptance criteria.

BRUNSWICK 1 J1 1-03936SRLR Reload 13 Rev. 1 Interim Corrective Action Stability GE SIL-380 recommendations and BWROG Interim Corrective Actions (BWROG-94079) have been in included in the Brunswick Unit 1 operating procedures. Regions of restricted operation defined to NRC Bulletin No 88-07, Supplement 1, Power Oscillations in Boiling Water Reactors (BWRs) and expanded in BWROG-94079, are applicable to Brunswick Unit 1.

16. Loss-of-Coolant Accident Results LOCA method used: SAFER/GESTR-LOCA The SAFER/GESTR-LOCA analysis results are presented in NEDC-31624P, '¶Brunswick Units I and 2 SAFER/GESTR-LOCA Loss-of Coolant Accident Analysis Application to GEl3 Fuel," Supplement 3, Revision 1, November 2000 and GE-NE-J1 103781-09-02P, "Brunswick Steam Electric Plant Units I and 2 ECCS-LOCA Evaluation for GE14," February 2001. The Licensing Basis Peak Cladding Temperature (PCT) is <17107F for GE13 fuel and <1580'F for GE14 fuel. The maximum local oxidation fraction is

<1% and the core-wide metal-water reaction is <0.1% for both fuel types. The initial operating MCPRs are 1.20 for GE13 and 1.275 for GE14 fuels.

The ECCS MAPLHGR multiplier for single loop operation (SLO) is 0.80 for both GE13 and GE14 fuels.

The ECCS-LOCA analysis for GEl3 fuel has been reviewed in light of the proposed improved LHGR limits for GEl 3 fuel. From this review it was determined that the limiting ECCS results were unaffected.

Thus the referenced LOCA results are still applicable with the improved GEl 3 LHGR limis.

A review of the Brunswick Unit 1 ECCS-LOCA analyses identified errors that have not been accounted for in the reference analyses for GE13 and GE14 fuels. The impact of applicable errors for GE13 and GE14 fuels are as follows:
